Abstract:
A power-factor correction circuit for a three-phase power supply is provided. The correction circuit includes a filtering unit at the input receiving the three phases of the current, at least one inductor per phase placed downstream of the filtering unit, a rectifying bridge powering a current-chopping stage. The filtering unit includes a differential-mode filtering cell including at least one inductive circuit formed of a single magnetic material in a double E, each leg of the E being surrounded by a winding.
